Conveying roller control part 58 is for carrying out the control of conveying roller 11 (motor etc. specifically for driving conveying roller 11).Warp beam control part 59 is for carrying out the control of section beam 3 (motor etc. specifically for driving section beam 3).

Secondly, step link yarn Y being wound in section beam 3 in warping machines 1 is described.Fig. 6 is the process chart of the step that the alignment forming the tieing k2 before initial spindle band B in warping machines 1 is shown.Fig. 7 is the figure of the situation of link yarn Y when illustrating that tieing k2 aligns.In addition, in order to easily observe accompanying drawing, give hatching to link yarn Y in the figure 7.

In warping machines 1, in order to link yarn Y being wound in section beam 3 on the basis making tieing k2 align, first, as shown in Fig. 6 (a), what utilize fluid cylinder 24 to make dance roller 23 rise to shown in Fig. 4 (a) above-mentionedly leaves position, in this condition, by the link yarn Y lodge that extracts from the multiple package P supported by bobbin cradle 2 in density reed 4, this link yarn Y is made to insert between fixed roll 22 and dance roller 23, further, by this link yarn lodge in density reed 6, on this basis link yarn Y is clipped between resilient roller 16a, 16b.

Secondly, as shown in Fig. 6 (b), utilize fluid cylinder 24 to make dance roller 23 drop to the above-mentioned slit forming position shown in Fig. 4 (b), thus, formed and make many link yarn Y insert the state of slit 26, make resilient roller 16a rotate in this condition.Now, width W 2 due to slit 26 is wider than the thickness Wy linking yarn Y and less than the knot Wa at the tieing k place linking yarn Y, therefore, as shown in Fig. 7 (a), many link yarn Y and are carried by towards right in figure (downstream of thread path), until the knot a2 at tieing k2 place arrives slit 26.

And then as shown in Fig. 7 (b), when the knot a2 at tieing k2 place arrives slit, knot a2 hooking, in slit 26, cannot be carried further and link yarn Y.Now, as mentioned above, due to for carry link yarn Y resilient roller 16a, 16b the part comprising surface be all made up of polyurethane elastomeric material, therefore clip the resilient roller 16a, the 16b that link yarn Y and linked yarn Y and press and elastic deformation.Therefore, the chucking power of resilient roller 16a, 16b clamping link yarn can not be so large as chucking power when the metal pair of rolls clamping link yarn Y utilized as rigid body.Therefore, even if make resilient roller 16a, 16b rotate after slit 26 further in knot a hooking, the power that resilient roller 16a, 16b tractive link yarn Y is weak, links yarn Y and slides on the surface of resilient roller 16a, 16b, and linking yarn Y can not be cut off.

Further, now, although resilient roller 16a, 16b tractive knot a hooking is weak in the power of the link yarn Y of slit 26, when utilize resilient roller 16a, 16b tractive reel yarn Y1 time, exist when the yarn Y1 of reeling is the low yarn of intensity and link the cut-off possibility of yarn Y.But in the present embodiment, be configured with the high polyfilament yarn of intensity that is high strength yarn Y2 in the end of the derivative side of link yarn Y of package P, high strength yarn Y2, by resilient roller 16a, 16b tractive, is cut off therefore, it is possible to prevent linking yarn Y.

Further, when continuing the conveying operation carrying out such link yarn Y, hooking increases gradually in the quantity of the knot a of slit 26, but when hooking is when the increasing number of the knot a2 of slit 26, knot a2 wants the size of the power boosted by dance roller 23 to increase.But, in the present embodiment, owing to utilizing the fluid cylinder 24 making dance roller 23 be elevated to press dance roller (being held in slit forming position) downward, therefore in fact dance roller 23 can not be wanted owing to tying a2 the power that boosted by dance roller 23 and move upward.Therefore, hooking is there will not be to be delivered to the situation in downstream through the slit 26 that width broadens because being boosted by knot a2 in the knot a of slit 26.

And then, when the knot a2 hooking that all link yarn Y are transported to tieing k2 place in the position of slit 26 thus link the alignment of yarn Y complete time resilient roller 16a is stopped the rotation.

Specifically, until the knot a2 hooking at tieing k2 place is in slit 26, all there is the yarns Y 21 in high strength yarn Y2 in the both sides of slit 26, therefore, optical sensor 31,32 both sides can both detect yarns Y 21.On the other hand, knot a2 hooking at tieing k2 place is under the state of slit 26, and yarns Y 21 is present in the right side of slit 26 and yarns Y 22 is present in the left side of slit 26, therefore, optical sensor 31 can detect yarns Y 21, but optical sensor 32 can't detect yarns Y 21.

Therefore, when become utilize optical sensor 31 detect with the yarns Y 21 of the identical number of link yarn Y of drawing and utilize optical sensor 32 to can't detect the state of any yarns Y22 time, the knot a2 that complete alignment part 57 of aliging detects the tieing k2 place of all link yarn Y all hooking in the situation of slit 26, situation that namely alignment of tieing k2 is complete.And then the now rotation of resilient roller 16a stops.

And then, after making tieing k2 alignment in the above described manner, what utilize fluid cylinder 24 again to make dance roller 23 rise to shown in Fig. 4 (a) above-mentionedly leaves position, on this basis, linking yarn Y by many is wrapping with in conveying roller 11 and section beam 3, make conveying roller 11 and section beam 3 rotate in this condition, thus many are linked yarn Y and be wound in section beam 3 and form spindle band B.Now, as mentioned above, owing to link yarn Y being wound in section beam 3 on the basis making tieing k2 align, the link yarn Y therefore forming spindle band B is wound in section beam 3 with the state starting the aligned in position reeled.

In addition, in this condition, the size Wa of the knot a located than tieing k due to the gap W1 between fixed roll 22 and dance roller 23 is large, therefore, the knot (omit and illustrate) of the tieing of the yarn when knot a3 at the tieing k3 place between yarns Y 21 and yarns Y 22, the knot a1 at the tieing k1 place between yarn Y1 and next yarns Y21 that reels and the yarn Y1 that reels are combined into by plurality of yarns by hooking, can not pass through between fixed roll 22 and dance roller 23.

Further, now, be provided with the part tapering 3a that then diameter is larger the closer to the end of section beam 3 in an end of section beam 3, many that are wound in section beam 3 link the direction overlap of yarn Y on the surface along this tapering 3a.

Secondly, complete afterwards until the action forming next spindle band B is described to the formation of spindle band B.Fig. 8 is the process chart that this step is shown.

Herein, for high strength yarn Y2, under state after the formation operation of spindle band B, the tieing k1 be wound between the winding yarn Y1 of section beam 3 and yarns Y 21 arrives than slit forming apparatus 5 also by the position on the right side of Fig. 8, further, the tieing k2 between yarns Y 21 and yarns Y 22 arrives than slit forming apparatus 5 also by the position in the left side of Fig. 8.

In warping machines 1, after the formation of spindle band B is complete, first, as shown in Fig. 8 (a), utilize cutter 8 will link yarn Y and cut off.Then, as shown in Fig. 8 (b), the basis making cutter 8 keep out of the way makes arm 33 swing, make suction nozzle 10 move thus until suction port 10a arrives the right side of resilient roller 16a, 16b, open valve 41,45 in this condition.Thus, the loose thread of the link yarn Y of upstream side is caught by suction nozzle 10 by attracting from suction port 10a, and by attracting from suction port 9a, unit 9 of being spliced catches the loose thread of the link yarn Y in downstream.Further, almost meanwhile, fluid cylinder 24 is utilized to make dance roller 23 drop to the above-mentioned slit forming position shown in Fig. 4 (b).

Secondly, resilient roller 16a is rotated.Thus, same with above-mentioned situation, many link yarn Y and are transferred until the knot a2 hooking of tieing k2 is in slit 26, and tieing k2 aligns.

Further, when this tieing k2 aligns, in knot a2 hooking under the state of slit 26, high strength yarn Y2 is by resilient roller 16a, 16b tractive, therefore, same with above-mentioned situation, links yarn Y cut-off situation when can prevent tieing from aliging.

Then, what utilize fluid cylinder 24 to make dance roller 23 rise to shown in Fig. 4 (a) above-mentionedly leaves position, then arm 33 is made to swing, the suction nozzle 10 of the loose thread of the link yarn Y of seizure upstream side is made to turn back to the suction port 10a position opposed with the suction port 9a of unit 9 of splicing, shutoff valve 45 on this basis, removes the seizure of suction nozzle 10 to the loose thread of link yarn Y.

So by attracting from suction port 9a, unit 9 of being spliced together with the link yarn Y in downstream catches the loose thread of the link yarn Y of the upstream side caught by suction nozzle 10.Then, open valve 43, fluid is flowed into splice unit 9, the link yarn that the flowing by this fluid twists order unit 9 inside is given and being interweaved, thus the loose thread of link yarn Y of upstream side after being alignd by tieing k2 and the loose thread of the link yarn Y in downstream gather and be bonded together.

And then, after the loose thread of upstream side and downstream is bonded together, shutoff valve 41, thus, remove unit 9 of splicing to the seizure linking yarn Y, section beam 3 after conveying roller 11 and position skew is rotated, thus, to reel plurality of yarns thus form next spindle band B with the spindle band B adjoining position being formed at section beam 3 last time.

Below, repeat same action, thus form multiple spindle band B successively at section beam 3.Herein, when forming spindle band when link yarn Y is wound in section beam 3, the length being wound in the link yarn Y of section beam 3 is quite long.Therefore, as mentioned above, even if made many position consistency starting to reel linking yarn Y before forming initial spindle band B, then many position offsets linked between yarn Y are larger for the position that distance starts to reel part far away.Therefore, if the alignment operation not carrying out tieing k2 as above whenever the formation operation of an end spindle band B just forms multiple spindle band B, then large position skew can be produced between many link yarn Y of the more late spindle band B formed.

But in the present embodiment, after formation spindle band B, carry out the alignment of tieing k2 before forming next spindle band B, therefore, the position consistency starting to reel in each spindle band B, can prevent from linking between yarn Y at many producing large position skew.

Further, in the present embodiment, as mentioned above, when making tieing k2 align, making many to link yarn Y and insert slit 26 and clamped by resilient roller 16a, 16b, in this condition, rotate by means of only making resilient roller 16a and just can automatically make tieing k2 align.Therefore, when carrying out the alignment of tieing k2, without the need to carrying out following numerous and diverse operation: under the state that many link yarn Y are inserted through slit 26, linking yarn Y to these many item by item and carrying out tractive, until knot a2 hooking is in slit 26.

And, from the view point of the miniaturization of device, expect to reduce the quantity of the package P being arranged at bobbin cradle 2, but, when reducing the quantity of package P, the number forming the link yarn Y of 1 spindle band B tails off, and the quantity being therefore formed at the spindle band B of section beam 3 becomes many, as a result, the number of times carrying out the alignment of tieing k2 increases.But, in the present embodiment, as mentioned above, automatically carry out the alignment of tieing k2, therefore, even if when making the increasing number of spindle band B because minimizing is arranged at the quantity of the package P of bobbin cradle 2, carrying out more than the change of the number of times of the alignment of tieing k2, the burden of operator also can not become large.

And, as mentioned above, resilient roller 16a, 16b, cutter 8, splice unit 9 and suction nozzle 10 only use when carrying out the alignment of tieing k2, therefore described above, these parts are configured on chassis 34, can share, therefore with other warping machines 1, in during link yarn Y being wound in section beam 3 in warping machines 1, can use above-mentioned parts in other warping machines 1, carry out the alignment of tieing k2.

Fig. 9 is the figure that the section beam 3 being formed with multiple spindle band B is shown.But, in order to easy understand accompanying drawing, in fig .9, decrease the quantity linking yarn Y and spindle band B compared with actual conditions, and broaden the interval linking yarn Y.Further, as previously described, when forming each spindle band B, the link yarn Y being wound in section beam 3 is overlapping in the direction on the surface along tapering 3a, but, illustrate in Fig. 9 and linked the situation of yarn Y in the radial direction overlap of section beam 3 in each spindle band B.

As shown in Fig. 9 (a), in section beam 3 after the formation of multiple spindle band B, part (in Fig. 9 (a) for the part B1 shown in thick line) between each spindle band B is cut off, and, as shown in Fig. 9 (b), drawn by the loose thread of the part after cut-out, many that will form each spindle band B thus link yarn Y extraction.And then, as shown in Fig. 9 (c), drawn link yarn Y is wound in beam of a loom 60.Now, be high strength yarn Y2 owing to linking between each spindle band B in yarn Y, therefore, after links yarn Y is drawn, be wrapping with before beam of a loom 60, the high strength yarn Y2 cut-out without the need to being wound in beam of a loom 60 is removed.

Secondly, illustrate and the variation after various change is applied to present embodiment.But, identical label is marked to the parts with the structure same with present embodiment and suitably omits the description.

In the present embodiment, optical sensor 31,32 is arranged on the left and right sides of slit forming apparatus, and yarns Y 21 and yarns Y 22 combine and the yarn be formed by connecting by high strength yarn Y2, the complete situation of the alignment of tieing k2 is detected according to the quantity of the yarns Y 21 utilizing optical sensor 31,32 to detect, but be not limited to this, such as, also can use and detect other device of the sensor that passes through of knot a2 and detect the complete situation of the alignment of tieing k2.

Further, in this case, high strength yarn Y2 also can be a continuous print yarn, and when high strength yarn Y2 is a continuous print yarn, the knot a2 hooking of the tieing k2 between high strength yarn Y2 and the winding yarn Y1 being connected to this high strength yarn Y2 is in slit 26.

Further, the complete checkout gear of alignment of the complete situation of alignment for detecting tieing k2 also can not be set.In this case, such as, link yarn Y near the visual confirmation slit 26 of operator, makes resilient roller 16a stop in the moment that the conveying of all link yarn Y stops, and makes fluid cylinder 24 action thus makes dance roller 23 increase.

And, in the present embodiment, in link yarn Y, to be reeled by 1 time and the winding yarn Y1 being wound in section beam 3 connects via high strength yarn Y2 each other, but, such as, in winding yarn Y1 is the situation of the winding yarn that intensity is high etc., also can be unworthy of setting high intensity yarn Y2, and winding yarn Y1 is connected to each other directly.But, in this case, need to make the length of each bar winding yarn Y longer than the length of the warp thread of spindle band B, so that when the formation of spindle band B is complete, the tieing k formed between the link yarn Y of this spindle band B and the link yarn Y forming next spindle band B arrives than slit forming apparatus 5 more by the position of the upstream side of thread path.

Further, in the present embodiment, resilient roller 16a, 16b, cutter 8, splice unit 9 and suction nozzle 10 are configured on chassis 34, move by making chassis 34, can share above-mentioned parts in multiple stage warping machines 1, but above-mentioned parts also can be fixed on warping machines 1.

Further, cutter 8 also can not be set, splice unit 9 and suction nozzle 10.In this case, such as, operator can carry out following operation by handwork: the cut-out of link yarn Y when carrying out the alignment of tieing k2 after the formation of spindle band B is complete and before forming next spindle band B, link the knotting of the seizure of yarn Y and the link yarn Y after cutting off.
